FoxFarm Beastie Bloomz - High-Phosphorus Soluble Bloom Fertilizer
Best for: growers wanting a concentrated phosphorus and potassium boost during the middle-to-late flowering weeks to support blossom and fruit development.
Our thoughts
This one is specifically Beastie Bloomz, FoxFarm's dry, high-phosphorus bloom booster, not a general soluble fertilizer range. As a powder, a small tub goes a long way compared with an equivalent liquid booster, which is reflected in the price. Use it as a targeted addition to your normal feed, not as a base nutrient on its own.
FoxFarm Beastie Bloomz is a water-soluble, high-phosphorus dry fertilizer, mixed into feed water to give plants a concentrated phosphorus and potassium boost during the blossom-development stage of flowering. Because it's a powder rather than a liquid, a relatively small amount dissolves into a large volume of feed water.
It's designed to be added alongside a base feeding programme during the middle-to-late weeks of flower, when the priority shifts toward supporting blossom and fruit development rather than vegetative growth.
How it compares
High-phosphorus bloom boosters are a well-established category, available as both liquids and powders.
- Vs FoxFarm's own liquid range (Grow Big, Big Bloom, Tiger Bloom): Beastie Bloomz is the dry, high-phosphorus specialist rather than a base feed, used as an addition rather than a replacement
- Vs Advanced Nutrients Big Bud or General Hydroponics FloraBloom: similar high-phosphorus bloom-booster role, different format, soluble powder rather than liquid
- Vs an equivalent volume of liquid bloom booster: a powder is cheaper to ship and store, which shows up as a lower cost per feed once mixed
If you're already feeding FoxFarm's liquid line, Beastie Bloomz slots in as the specialist bloom addition. If you're on a different brand, it works fine as a standalone high-P powder booster too.
Usage guidance
Powders need dissolving properly and dosing carefully, since a small measure covers a lot of feed water.
Mixing
Dissolve fully in warm water before adding to your main feed solution, undissolved powder can settle in a reservoir or clog fine drippers.
Timing
Introduce during the middle-to-late weeks of flowering, when blossom and fruit development is the priority rather than vegetative growth.
Combining with a base feed
Use as an addition to your existing base nutrients, not as a replacement, high-phosphorus boosters are formulated to supplement rather than provide a complete feed on their own.
Technical specifications
- Format: water-soluble powder
- Analysis: high-phosphorus, high-potassium (0-50-30 as published by FoxFarm)
- Growth stage: middle to late flowering
- Mixed with: feed water
- Brand: FoxFarm
Who this is for
- Growers wanting a concentrated bloom boost during mid-to-late flower
- Anyone already on FoxFarm's liquid feeding line looking for a matched addition
- Growers who prefer a powder booster for cost and storage reasons
Best suited to use as a targeted addition during flowering, not as a standalone base feed.
Our take
It's a specialist, high-strength addition rather than an everyday feed, and it's best used exactly where FoxFarm intends it, during the blossom-development weeks of flower. As a powder, it's a cost-effective way to add a concentrated P and K boost without buying a large volume of liquid booster.
One we sell a lot of to growers running a FoxFarm feeding schedule. Worth adding for the flowering weeks it's built for.
